WICK-STOP LAMP-BURNER.

Specification of Letters Patent.

Patented May 3, 1910.

To all whom it may concern.

Be it known that I, EDWARD S. SANDER- SON, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Wick-Stop Lam -Burners, of which the folto has been in a measure alleviated by lowing is a ful, clear, and exact description.

This invention relates to lamp burners which emplo a wick, and in which the wick is raise or lowered by means of starwheels mounted on a rotary shaft. Lamps having such burners and used in positions where they are subjected to considerable or violent agitation or motion, are apt to have their wicks jostled out of place and either raised or lowered, in either case interfering with proper illumination. This is notably true where such lamps are used in connection with switch, signal, and sema hore work; the vibration imparted to the amps from the movement of heavy trains, causing an automatic movement of the wick-raiser that interferes with the illuminating efficiency of the lamp. The difficulty referrield t e application of some sort of stop, or friction device, to the wick, or to the wick-raiser.

The object of the present invention is to provide a simple and efficient wick-stop that readily adjusts itself to wick-shafts of various diameters and various makes, and applies in a practical way suflicient tension to the wick-shaft to hold the wick in any given adjusted position, without the liability of such adjustment being disturbed by the movements to which the burner may be subjected in use.

The invention consists of a s ring clip, preferably of flat spring meta such as brass, having substantially an open tubelike portion adapted to embrace the wickraiser shaft and provided with diverging arms which engage adjacent parts of the lam -burner for the double purpose of hol ing the clip in place, and of applying tension through it to the said shaft, all as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure l is a side elevation of a lampburner in common use, and supplied with the wick-stop of this invention. Fig. 2 is a vertical sectlon, taken substantially at right angles to the view shown in Fig. 1. Fig. 3 is a bottom lan view of the upper part of the burner detached. Fig. 4 is a top plan view of the lower or collar part of the burner detached. Fig. 5 is a top plan view of the wick-raiser and clip detached. Fig. 6 is a perspective view of the clip detached.

The top portion 1 of the lamp-burner and the bottom or collar portion 2 thereof, may be of any ap roved construction, and these parts are pre erably connected by means of lugs 3 on the collar portion engaging slots 4 in the bottom of the upper portion turned over or clenched, as shown at 3 in Fig. 2. The top portion 1 is made with a shoulder 5, and the bottom or collar portion is made with a shoulder 6.

The wick-raiser shaft 7 is supplied with the usual star-wheels 8 and an operating disk 9. This shaft is arranged in the collar portion of the burner in such position that 1ts star-wheels project through slots into the wick-tube 10 in order to engage the wick, so as to raise or lower it as desired.

If a wick-raiser of the character described be used without any friction device, the agitation or vibration to which the lamp may be subjected frequently displaces the wick and thus interferes with the illumination desired. In order to correct and obviate this displacement, I employ the clip shown in Figs. 2, 5 and 6, which may be made of a fiat piece of 5 ring metal, such as brass, formed at one en as a tube 11 which is open at one side, and having its other ends 12 made as divergent arms. The clip is applied to the shaft 7 preferably between the star-wheels 8 so as to keep it in place and prevent its longitudinal movement on the shaft, and its diverging arms 12 extend in between the shoulders 5 and 6 of the upper and lower parts of the burner, respectively, and are by these shoulders ut under tension sufiicient to bind the sha 7 a ainst accidental rotation, while not inter ering materially with the hand operation of the shaft necessary to raise or lower the wick.

By this construction of wick-stop it is made adaptable to shafts of different diameters and makes, and a perfectly eflicient defense is afforded against the accidental move- 15 and lower portions provided with opposite ment of the wick when the lamp is exposed to violent motion or agitation, when used in railway signal, switch, and semaphore work,

and in similar or exposed places; and, moreover, the wick-stop is held in place and against accidental displacement.

What I claim is 1. A wick-stop lamp-burner, having shoulshoulders, a wick-raiser comprising a shaft and star-wheels thereon and a friction device composed of an open tube-like portion embracing the shaft between the star-wheels and having diverging arms engaged and 20 I held under tension by and between the said shoulders.

In testimony whereof I have hereunto set my hand this 24th day of January A. D. 1910.
